Short answer: the Martin Audio CDD6 for better sound quality, the Martin Audio CDD5 for the lower price. The Martin Audio CDD6 ranks #7 of 26 surface-mount and background music speakers, rated 3.1/5, at $550. The Martin Audio CDD5 ranks #11, rated 3.0/5, at $315, $235 cheaper.
What the Martin Audio CDD6 does well: A passive Coaxial Differential Dispersion speaker from the same Martin Audio CDD line as the measured Martin Audio CDD8 and Martin Audio CDD10: a 6.5” coaxial driver in a cabinet small enough for discreet installs. Watch for: No independent measurements yet, so it can’t be compared with ranked PA speakers.
What the Martin Audio CDD5 does well: A passive Coaxial Differential Dispersion speaker from the same Martin Audio CDD line as the measured Martin Audio CDD8 and Martin Audio CDD10: the smallest model, a 5.25” coaxial driver in an ultra-compact on-wall cabinet. The tradeoff: No independent measurements yet, so it can’t be compared with ranked PA speakers.
Buy the Martin Audio CDD6 if sound quality matters more than the price. Buy the Martin Audio CDD5 if the price matters more than sound quality.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Martin Audio CDD6 2.7 to 3.5; Martin Audio CDD5 2.6 to 3.4). Treat this verdict as provisional.

Martin Audio CDD6: $550.00 each Passive Estimated Full Compass eBay
Same family: the Martin Audio CDD-LIVE 8 (smallest powered model, estimated 3.4/5), the Martin Audio CDD-LIVE 12 (powered model, estimated 3.1/5), the Martin Audio CDD-LIVE 15 (largest powered model, estimated 3.5/5), the Martin Audio CDD5 (smaller passive model, ranked lower, estimated 3/5), the Martin Audio CDD8 (larger passive model, rated 3.2/5), the Martin Audio CDD10 (larger passive model, rated 3.1/5), the Martin Audio CDD12 (larger passive model, rated 2.9/5) and the Martin Audio CDD15 (larger passive model, rated 3.3/5).
Pros: A passive Coaxial Differential Dispersion speaker from the same Martin Audio CDD line as the measured Martin Audio CDD8 and Martin Audio CDD10: a 6.5” coaxial driver in a cabinet small enough for discreet installs. CDD widens the horizontal pattern close to the speaker and narrows it with distance, which keeps level more even from front to back of a room.
Cons: No independent measurements yet, so it can’t be compared with ranked PA speakers. It needs an external amplifier, and its small woofer limits bass and output, so larger rooms need a subwoofer or bigger CDD models.
